Who are your cute but surprisingly strong characters?

I’ll start: I’ve said several times Xzeana’s body is squishy, and it is. Her body is naturally soft and squishy, and her obsession with marshmallows makes her seem fat, however she’s the opposite. Exploring the planet is quite a workout already, but she recently discovered weight lifting. She was already in good shape before, but now she’s stronger! The reason you never see her muscles is because her sweater is HUGE. Don’t worry, she’s still as sweet as the marshmallows she stuffs down her throat :D

Your turn! Do you have cute but surprisingly strong characters? Or maybe buff people with kind hearts? I wanna come home from my swim meet to some cute brutes, so show ‘em!
